LONG story short, just finished replacing a bad rocker and intake cam. Closed everything up and it wouldn't start. I could hear the starter motor clicking, and the belt was going around, so I believe the starter is trying.
Searching threads found how to bypass the immobilizer, but more importantly the inertia switch. Got home today, reset the switch (actually heard and felt it click) and tried again. Still no dice.
Pulling the plugs out, they are wet and have a heavy smell of gas (unlike yesterday) so I know the engine is now getting fuel. Pulled the spark plug, put it back in the ignition coil/igniter (sorry, not a mechanic, so I'm not sure what it's called) then grounded it to the neg terminal on the battery, no spark when pressing start button.
Back to LT forums and found another thread that was solved by cleaning the contacts on the intake cam position sensor. Thread mentioned that if they disconnected the sensor it would fire but run like dirt. Tried disconnecting it, still no firing.
Not sure how to test the outputs from the ECU (I do have a multimeter) as I'm not sure which pins I need to test.
When I was replacing the cam/rockers, I tried to not take apart anything I didn't need to since I'm not a mechanic. This means that I basically removed the plugs and wires, valve cover, the Oil Control Valve housing and the cams/rockers. Battery was disconnected the whole time, but was flat when I put it back in. Had it jumpped to my other car (running) so I am getting a 13v measurement from the posts.
So, two questions, what pins should I measure on the ECU? and any other thoughts or things to check?
Appreciate any help anyone can offer.
Edit: I did test a bunch of different fuses (I believe R6 or R7 is the one a lot of people point out) and they all tested fine. Everything in the car powers on as far as I can tell (except the amp since it's currently disconnected).
